Denton is roughly an hour's drive north from both Dallas and Fort Worth.
A new train service, the A-Train, operates commuter trains that connect to Dallas from Denton (adult/child $5/1.25). Trains run every half hour Monday to Friday and every two hours on Saturday. To reach Dallas, change from the A-Train to the DART light rail Green Line at the Trinity Mills Station. The total transit time is about 90 minutes.
